FIRE EXTINGUISHER HANGER Filed Feb. 16. 1953 2 Sheets-Sheet 2 A itorneyBarney Schmansky,.1fontiac, Mich. i J Application e ruary 16, 1933.:Serial 5. 657,141 4 Claims. (01; 248-) My present application is filedinthe place and stead. of my abandoned application filed Nov. 22,1929,,Serial No. 409,029.

.Thisinvention relates to a contrivance which may be convenientlyreferred to as a hanger, the same being expressly constructed forsupporting a chemical fire extinguisher of the type used in publicbuildings, oilices, homes and elsewhere.

As. a general. rulegpthe chemical fire extinguisher is provided with oneor more handlelike bails, one of which is engaged over a suspension orhanger hook on anv appropriate sup porting surface disposed in readinessfor use in case of emergency.

The purpose of the present invention is to provide a new type of hangerwhich is in the nature of a safety appliance permitting the fireextinguisher to be successfully suspended in an inactivestate so long asit is in condition for use; that is, filled with the chemicals, but soconstructed as to prevent replacement of the extinguisher by untrainedhands, or to permit replacement of a used extinguisher.

The idea involved in this arrangement is to avoid the hanging on thehook, of an extinguisher which was previously used and which is not incondition for reuse so as to avoid a catastrophe, and tomake itnecessary to replace the used extinguisher with one which is incondition foractionin case of a subsequent emergency or fire.

Briefly, this idea is involved in a structure including a key-controlleddevice which is automatic in the sense that as soon as the fireextinguisher is removed from the hanger, the latter will becomeineffective through the automatic action of a retracting and retaininglock. Thus, in order'to render the hanger again-available, it isnecessary to unlock it, this being done by an authorized person, so thatit will be in proper condition for -re-use when another emergencyarisesa The particular structure for accomplishing these results willbecome more readily apparent from the following description anddrawings.

Figure 5 is a side view of the shackle cf the l'ock.-.

Figure -7 is a front view of Figure 6, observing in a direction fromleft to right.

In the drawings, the reference character 8 designates a plate on which asubstantially rectangular box-like housing 9 is mounted. This housing isformed in the top with a key entrance hole 10. The front is providedwith a slot as at 11 to. facilitate entrance of the handle 12 onthe fireextinguisher 13 as seen in Figure 4. The side walls of the housing arecut away to form hooks 14 which when uncovered 7 receive the handle '12as shown in Figure 4.

'key in the possession of an authorized ofiicer or I Inside of thehousing is a suitable lock casing 15 having a key-hole 16, Figure 2, forreception of an appropriate key 17 as indicated in dotted lines inFigure 1. The lock includes a U-shaped shackle 18 which is provided witha stem 19 as seen in Figure 7, having upper and lower fingers;

20 and 20a which function as keepers. These engage over thechannel-shaped portion 21 of the cover plate. The cover plate is in thenature ofa slide 22 of channel-shaped design mounted for sliding actioninside of the housing and it includes a lower portion 23 to serve as ashutter for the slot 11 and the hooks 14 as well as an extension shelfor flange 24.

Inside of the casing are lifting coiled springs 25 which serve to liftthe shutter to closing positionand to cause it to be locked as theshackle 18 moves into the lock casing 15. Thus the shackle is thusrendered ready for receiving the suspension element 12 of theextinguisher 13 as shown in Figure 4. This renders the extinguisherready for removal in case of fire. 1

As soon however, as the extinguisher is lifted out'of the slot andremoved from the hooks 14, the springs 25 come into play and slide theshutter up to the position shown in Figure 3, thus covering the, slotand the hooks for preventing accidental or thoughtless replacement ofthe used extinguisher. This avoids a catastrophe such as box-likehousing provided A careful consideration of the description inconnection with the drawings will enable the, reader to obtain a clearunderstanding of the construction, arrangements, and features andadvantages therefore, a more lengthy description is regarded asunnecessary.

Minor changes in shape, size and rearrange-.

ment of details coming within the field of inven tion claimed may beresorted to in actual practice if desired.

What is claimed is:

1. In a hanger of the class described, a hollow V with a handlereceiving slot and suspension hooks at the opposite ends of said slot, aspring pressed slide in said housing including a shutter plate adaptedto entirely cover said slot and hooks, a lock casing in said housingincluding a shackle having operating connection with said slide.

2. In a hanger and in combination, a housing having a slot in one of itswalls and also having hook means in communication with said slot andclosed when the slot is closed, a spring influenced shutter arranged inone position to close said slot, and lock-controlled means forpreventing movement of the shutter from said position save when the lockis actuated by its complementary key.

3. In a hanger and in combination, a housing having a slot in one of itswalls and also having hook means in communication with said "slot andclosed when the slot is closed, aspring influenced shutter arranged inone position to close said slot, and lock-controlled means forpreventing movement of the shutter from said position save when the lockis actuated by its complementary key; said shutter having a projectionextending through and movable in said slot.

l. In a hanger and in combination, a housing having a'slot in one of itswalls and also having hook means in communication with said slot, aspring influenced shutter movable in the housing and having'a'U-shaped'inwardly extending portion and also having a projectionextending through and movable in the slot, said'shu'tter adapted in oneposition to closesaid slot, and lockcontrolled means engaging said U-shaped portion for preventing movement of the shutter from said positionsave when the lock is actuated by its complementary key.
